Hi OldCoder,This may be a stupid idea, but here it is...
How about a smart, translating BMS? It seems that maybe a new smart battery module could be made that uses a micro Arduino connected to the original 3DR Solo battery BMS, which reads the new battery data and then emulates the original BMS for the 3DR Solo, sending translated and scaled battery data appropriately?
The Arduino code could scale the battery capacity so that a full 10,000 Mah pack would look like a full 5,000 Mah pack to the 3DR Solo? You could scale the reported Mah remaining, and you could also scale the battery voltages, to make return to land happen at the correct voltage for a new battery chemistry?
In theory, it seems that this could work without adding wires to the Solo Cube?
I have been working on something like that. It uses the voltage to determine remaining capacity rather than measuring actual capacity used. This way you can use any sized pack and it will send through remaining capacity based on a max voltage for 100% and min voltage for 0%.
Generic Battery + Arduino = Happy Solo
